$4$ from outside the mitochondria and $34$ from within the mitochondria.

Vedclass · Answer

(B) The complete oxidation of one glucose molecule yields a net gain of $38 \,ATP$ in prokaryotes (or under specific shuttle conditions in eukaryotes). $1$. Glycolysis produces $2 \,ATP$ directly and $2 \,NADH$. $2$. The link reaction produces $2 \,NADH$. $3$. The Krebs cycle produces $2 \,GTP$ (equivalent to $ATP$),$6 \,NADH$,and $2 \,FADH_2$. $4$. In the Electron Transport System $(ETS)$,each $NADH$ produces $3 \,ATP$ and each $FADH_2$ produces $2 \,ATP$. $5$. Total $ATP$ calculation: $2 \,ATP$ (glycolysis) + $2 \,GTP$ (Krebs) + $10 \,NADH 	imes 3 = 30 \,ATP$ + $2 \,FADH_2 	imes 2 = 4 \,ATP$. $6$. Thus,$2 + 2 + 30 + 4 = 38 \,ATP$. $7$. Specifically,$4 \,ATP$ are produced via substrate-level phosphorylation (outside mitochondria in glycolysis and inside in Krebs),and $34 \,ATP$ are produced via oxidative phosphorylation in the mitochondria.

How are $38 \,ATP$ molecules produced during the respiration of a single glucose molecule?
